What is the name of the cell line derived from Henrietta Lacks that is still used in research today?

• HeLa cells

• HL-60 cells

• Jurkat cells

• CHO cells

Which of the following best describes the difference between lytic and lysogenic viral replication cycles?

• Lytic cycle destroys the host cell, lysogenic cycle integrates viral DNA into the host genome

• Lytic cycle integrates viral DNA, lysogenic cycle destroys the host cell

• Both cycles destroy the host cell immediately

• Both cycles integrate viral DNA into the host genome

Compare the chromosome number in daughter cells produced by mitosis and meiosis.

• Both have double the original number

• Mitosis produces cells with the same number, meiosis with half

• Mitosis produces cells with half, meiosis with the same number

• Both have half the original number
